IPC: C04B18/04
Filed: 1992-02-04
Abstract: PURPOSE:To improve productivity by cooling molten slag at the cooling rates corresponding to prescribed CaO/SiO2 weight ratios, thereby specifying crystalline quality to a specific volumetric ratio. CONSTITUTION:The molten slag S of raw material ashes is packed into plural molds 4d placed on a chain conveyor 4 in an obliquely disposed casing 2 and is transported. A high-temp. exhaust gas is introduced from an ejector 6 in the central part into the casing 2 to maintain the within thereof at a prescribed temp. The molten slag S is cooled at the rates of <=0.4 deg.C/min when the CaO/ SiO2 weight ratio of the raw material ashes is below 0.9 in 1000 to 1200 deg.C region including the crystallization point of the molten slag S' at <=0.7 deg.C/min when 0.9 to 1.0, <=1.5 deg.C/min when 1.0 to 1.1, <=2.0 deg.C/min when 1.1 to 1.2, <=3.0 deg.C/min when 1.2 to 1.3, and <=5.0 deg.C/min when >=1.3, thereby 15 to 54vol.% of the ash is crystalized. The mold 4d arriving at the transportation destination is turned over to drop the solidified slag C from a discharge port 2a into a solidified slag container 5, by which the base course material is obtd.

IPC: G06F13/38
Filed: 1987-01-28
Abstract: PURPOSE:To transfer data at high speed and to realize an effective system operation by transferring the address and control signals between two ports selected among plural ports and transferring data without changing the data. CONSTITUTION:When signals phi1 and phi2 are set at low and high levels respectively, an output driver 105 is set at a high level. Thus an output driver 106 receives the output of a 1st inverter 104 and outputs the address and control signals of a 1st port 100 to a terminal 107. Then the signals phi7 and phi10 are set at low levels together with signals phi8 and phi9 set at high levels respectively, a 5th inverter 123 and a 6th output driver 126 are set at high impedances. Then a 6th inverter 125 outputs the data on the 2nd port 101 of a terminal 127 to a 3rd output driver 124. In such a way, the address and control signals are transferred to a port from another port to realize the input/output of data. Thus the data can be transferred at high speed and a system is operated with high efficiency.

Abstract: PURPOSE:An extract of yellow pigment obtained from fruits of Cape jasmine is subjected to ultrafiltration with a membrane of a specific fractionation molecular weight to remove iridoid glucosides and other impurities, thus giving the titled pigment, in high efficiency, which is almost free from odor, bitter taste and discoloration and is used as a yellow pigment for food. CONSTITUTION:The fruits of Cape jasmine are crushed, combined with water, stirred, then the residue is filtered off to obtain an extract of the yellow pigment. The extract is concentrated by means of a spiral membrane module filled with an ultrafiltration membrane of 2,000-20,000 fractionation molecular weight to effect selective filtration of iridoid glucosides and other impurities. The resultant concentrate is dried, e.g., by spray-drying to give the objective pigment. In another manner, the concentrate is diluted with distilled water and subjected to ultrafiltration again to give the objective pigment of high purity.

IPC: H01L21/3065
Filed: 1990-01-29
Abstract: PURPOSE:To prevent undercut induced by scattered active species by discharging mixed etching ga to which inactive dilution gas is added in an ECR ion source. CONSTITUTION:As impurities, phosphorous is added to an oxidizing silicon film 1 which forms an offset region. When a polysilicon film 2 is deposited thereon, mask patterns are formed on the silicon film by a photo resist film 3. Cl2 is used as an etching gas while N2 gas is used as a dilution gas. Under the pressure of 0.05Torr, the plasma generated in an ECR ion source is converged by a magnetic field and introduced into an etching chamber where etching is carried out. Then, a favorable etching shape, which is virtually free of undercut, is available. It is, therefore, possible to inhibit undercut induced by scattered active species.

Abstract: PROBLEM TO BE SOLVED: To calibrate the reference of the optical axis of an optical axis deviation angle measuring instrument, using a semiconductor laser which has an unknown optical axis deviation angle. SOLUTION: The temporary reference S of the optical axis of an optical axis deviation angle measuring instrument is set, and based on the set temporary reference S of the optial axis, the first optical axis deviation angle Δθ1 of a semiconductor laser 20 for calibration is measured with a photodiode 32, and the second optical axis deviation angle Δθ2 is measured again with the photodiode 32, in a state that the semiconductor laser 20 is rotated 180 deg., and the true reference S0 of the optical axis of an optical axis deviation angle measuring instrument is obtained from the average value of that measured optical axis deviation angle measuring instrument.  At this time, the angle Δθm formed between the true reference S0 of the optical axis of the optical axis deviation angle measuring instrument and the temporary refernece S of the optical axis is given by an equation Δθm=(Δθ1 +Δθ2 )/2. On the stage of obtaining the average value, the true optical axis deviation angel Δθ of the semiconductor laser 20 is negated, so there is no necessity of the true optical axis deviation angle Δθ being known.

IPC: G11B7/24091
Filed: 1994-02-17
Abstract: PURPOSE:To prevent excessive diminishing of tracking error signals even in a prepit region and to increase a user data region by arranging prepits by shifting their centers from a land center. CONSTITUTION:An optical master disk arranged by shifting the position of pits 2 alternately and successively with respect to the center line of the land is produced. Further, a stamper is produced from this master disk and a substrate is produced from this stamper. The amplitude of the tracking error signal at the time of passing the preit region is improved with substantially no degradation in the prepit signal if such substrate is used. In such a case, an offset arises in proportion to the deviation from the center line 3 of the land 4 of the preits in the tracking error signal at the time of tracing but the codes of the offset are alternately reversed and, therefore, the offset generated by a substantial failure in follow-up is extremely small and an optical head has substantially no deviation with the center of the land.

Abstract: PROBLEM TO BE SOLVED: To reduce a swivel radius and permit swivel at a narrow place by rotating a rotating bracket to a boom with a jib bent downwards and its end positioned on the extension of the center line of the rotating axis of a rotating and jointing device. SOLUTION: When a multistage boom overhangs toward a working position on the extension in its longitudinal direction from its storage position at the side of the multistage boom, the multistage boom is derricked and a top boom 5 is extended. To rotate a jib 51 downwards, a hydraulic cylinder 50 for derricking is contracted to the minimum stroke to position the top end Tb of the jib 51 on the extension of the rotating axis V-V of a rotating and jointing device 40. Under this condition, a rotating bracket 20 and the jib 51 are rotated by a rotating device 30 so as to obtain a condition on the extension in the longitudinal direction of the multistage boom from the condition of a storage position at the side of the multistage boom. The rotational radius of the jib end part Tb is within the maximum width of the jib, thus it is possible to conduct work with high safety.
